Discussion on the problem of converting front-end js objects into java objects in the background_javascript skills

During the recent project development process, I encountered the problem of converting the front-end js objects into java objects in the background many times. Record the method for later use.

To put it simply, use the JSON.stringify() method in the frontend to convert the js object into a js string, and receive the json string in the background and convert it into a javaBean.

Frontend code:

Copy code The code is as follows:

var data = {};
data.id = $('#id').val();
data.msg = $('#msg').val();

//Submit data
$.post(contextPath '/XXX.do?' new Date().getTime(),{data: JSON.stringify(data)},function(result){
alert(result);
});

Backend code:

Copy code The code is as follows:

@RequestMapping("/XXX")
public void save(HttpservletResponse response,String data){
if(!StringUtils.isEmpty(data)){

//json Convert string to javaBean
Msg msg = (Msg) JSONObject.toBean(JSONObject.fromObject(data),Msg.class);

......
}
}
